AutoCAD is a commercial computer-aided design (CAD) and drafting software application by Autodesk. The first release of the software started with version 1.0 in December 1982.[1] The software has been continuously updated since its initial release.

AutoCAD opens documents with DWG compatibility as a "DWG file format version code" where the specific version code can be found by opening the .dwg file in Windows Notepad or any text editor program. The file format version code is dependent on the AutoCAD version.[2]
